Metal lawn and garden edging: the hidden knife?

OBJECTIVE: Lacerations account for many visits to the pediatric emergency department. We observed children presenting to local emergency departments in a large metropolitan area with lacerations incurred from metal lawn and garden edging, a landscaping tool. We sought to describe the severity of lacerations caused by metal edging, the characteristics of wound repair, and the need for subspecialty consultation. DESIGN: A retrospective chart review including all pediatric patients (< 18 years) presenting with lacerations caused by metal lawn and garden edging from January 1995 to October 1997 was performed. Patients were seen at one of three emergency departments in Colorado. RESULTS: One hundred twenty-six patients were enrolled (76% male, 24% female), with a median age of 9 years. The most frequent location of laceration was the foot (40%), followed by the knee (26%). The median length of laceration was 3 cm (range 1-22 cm). Sixteen patients (13%) received either intravenous or oral antibiotics, and six patients (5%) received orthopedic evaluation. CONCLUSIONS: Metal lawn and garden edging in landscaped neighborhoods presents a previously undescribed laceration danger to children. Some lacerations sustained from the metal lawn edging are extensive, receiving either multiple layer closure and/or the need for subspecialty consultation.     

Efficacy of TAC topical anesthetic for repair of pediatric lacerations

A prospective evaluation of 103 consecutive children who received TAC (tetracaine, epinephrine [adrenaline], cocaine) liquid topical anesthetic for the repair of their minor dermal lacerations was performed. A unique method of TAC application was used that consisted of applying the medication to the inner margins of the wound cavity and allowing it to stand for several minutes prior to the application of a TAC-saturated gauze pad to the wound surface. Of 670 sutures placed, 637 (95%) were done without eliciting pain. The TAC topical anesthetic was more than 95% effective in providing complete anesthesia for wounds located on the face and lip; it was equally efficacious in anesthetizing larger wounds (greater than or equal to 5 cm in length and/or greater than or equal to 5 mm in depth). No adverse reactions resulted from the application of TAC. A single wound healing complication occurred in 103 patients. TAC is a safe, effective method for anesthetizing minor lacerations of the skin in children. Its painless method of application relieves patient discomfort and maximizes patient compliance during the repair procedure, both of which enhance the accurate approximation of lacerated tissue.     

A comparison of three formulations of TAC (tetracaine, adrenalin, cocaine) for anesthesia of minor lacerations in children

A randomized, prospective, double-blind study comparing three formulations of the topical anesthetic solution TAC for laceration repair was undertaken in 250 children. The children's wounds were anesthetized with either TAC I (original formulation--0.5% tetracaine, 1:2000 Adrenalin, 11.8% cocaine), TAC II (1.0% tetracaine, 1:4000 Adrenalin, 7.0% cocaine), or TAC III (1.0% tetracaine, 1:4000 Adrenalin, 4.0% cocaine) prior to repair. The solutions were compared with respect to efficacy, acceptability, wound complications, and side effects. We found comparable efficacy of the three formulations, with similar efficacy to 1% lidocaine infiltration for facial and scalp wounds. Anesthesia for extremity wounds was adequate in only 39.9% of cases, regardless of TAC strength. Wound complications and side effects were within expected and acceptable limits. Our findings support use of TAC for face and scalp lacerations and a change to a less concentrated TAC preparation, such as our "TAC III," which is presumably safer for widespread use.     

Half-strength TAC topical anesthetic. For selected dermal lacerations

A prospective evaluation of 75 consecutive children with lacerations of the face, lip, and scalp who received TAC (tetracaine, epinephrine [adrenalin], cocaine) topical anesthetic for the repair of their wound was performed. The TAC preparation contained one-half the conventional concentration of cocaine (5.9%) and tetracaine (0.25%) previously used in other studies that have evaluated its anesthetic efficacy. A maximal dosage of 3 ml of TAC (containing 175 mg cocaine and 7.5 mg tetracaine) was applied to each laceration. The diluted TAC preparation provided complete anesthesia for approximately 95% of the more than 400 sutures placed. No adverse reactions were noted in any patient who received TAC, and in no instance did a complication of wound healing occur. The original formulation of TAC was arbitrarily composed, and the maximum concentration per dosage of the potentially toxic component medications of TAC that can be "safely" applied to dermal lacerations in children remains to be defined. Utilization of this diluted preparation will diminish the risk of potential systemic toxicity from the absorbed component medications of TAC without compromising anesthetic efficacy.     

Repair of compound-depressed skull fractures in children with replacement of bone fragments

A retrospective study of 31 consecutive cases of compound-depressed skull fractures treated by bone fragment replacement between October 1983 and August 1990 was performed. Epidemiology, clinical features, therapy, and outcome were examined and compared with previous series. A protocol is presented for bone fragment treatment intraoperatively and use of intravenous antibiotics (nafcillin and Claforan) perioperatively, despite the degree of wound contamination or dural violation. Of the 31 cases, 15 had dural lacerations with 4 of these requiring patching with pericranium. The degree of wound contamination varied, with only 8 cases considered clean. The average age of patients treated was 8.6 years. At follow-up (average of 26.5 months), all patients had solid bone fusions and well-healed wounds. There were no instances of wound infection or osteomyelitis. No patient required subsequent cranioplasty. It is proposed that bone fragment removal for compound-depressed skull fractures, regardless of the degree of contamination, the presence of dural laceration, or the degree of intracerebral injury, is not necessary and that bone fragment replacement avoids a second operation for cranioplasty.     

New concepts in wound management

Children with lacerations and other minor wounds are among the most often encountered in the ED. The steps in management of these patients are well-known and often well-researched, but dogma still permeates the process. Local anesthetics are effective, and several choices are available. New topical creams and expanded indications for the currently available anesthetics will enhance patient comfort during laceration cleaning and repair. Irrigation with tap water is a safe, effective and economic method of cleaning wounds, and perhaps even the use of sterile gloves is superfluous in preventing wound contamination. Several alternative wound-closure materials are currently available including tissue adhesive in an array of applicators and formulations, adhesive strips, staples, and nonabsorbable as well as absorbable suture material. Finally, prophylaxis for tetanus is a simple, if possibly underused, technique. Further research into new materials and procedures will only improve our care of patients who have sustained skin trauma.     

Influence of topical anesthesia on the sedation of pediatric emergency department patients with lacerations

Local anesthetic infiltration of wounds causes pain which distresses children. A painless topical anesthetic solution containing tetracaine, adrenaline, and cocaine (TAC) may reduce this distress. We hypothesized that the use of TAC for anesthesia may reduce the utilization of sedation for laceration repair. We performed a retrospective review of all pediatric emergency department (PED) patients receiving parenteral meperidine, promethazine, and chlorpromazine (DPT) during the period after TAC became routinely available. For comparison, data from a recent retrospective study of DPT (preTAC) use in the same PED were used. There was a reduction in the percent of total PED patients receiving DPT, from 1.7% preTAC to 1.2% during the TAC period (P less than 0.05). During the TAC period, there were no significant changes in patient volume or case-mix indicators. Of the major indications for DPT, there was no significant change in the percent receiving DPT for fractures, abscesses, burns, foreign body removal, or head injuries. However, there was a significant reduction in the percent of patients with lacerations receiving DPT during the experimental period, from 12% to 7.6% (P less than 0.05). There were no significant differences in laceration frequency (119/mo and 116/mo), length (2.7 and 2.7 cm), location (85% and 93% total for face and digits), or complexity (64% and 63%) for preTAC and TAC periods, respectively. We conclude that TAC used for local anesthesia may reduce the need for sedation in PED patients with lacerations that require suturing.     

Human bites in children.

Human bites are common during childhood and usually result from fights or aggressive play with another child. Bites may present as indentation marks, scratches, abrasions, contusions, or lacerations. Most human bite wounds are sustained on the upper extremities, followed by the face and neck, the trunk, and the lower extremities. Infection is the most common complication. Cultures of an infected bite wound yield an average of five microorganisms. This article reviews the current recommendations on the management of human bite wounds in children.     

Human bites in children

We studied 40 children aged four months to 18 years seen in the Emergency Department (ED) to determine the spectrum of human bites and the incidence of infection in treated and untreated wounds. Initial data concerning time elapsed until a physician examined the bite, site and size of the bite, whether the bite was infected when first seen, and whether antibiotics were prescribed, were obtained from the ED chart. Follow-up by phone or mail was available on 33 of the 40 children. The incidence of human bites was one in 600 visits. The commonest lesion was a superficial abrasion of the face, inflicted by another child. Twenty-nine of the 33 bites were uninfected when first seen; 13 of them received no antibiotics; and 16 received oral antibiotics. There was no significant difference in mean age, sex, site, or type of wound between these two groups. None of 13 untreated and one of 16 treated children developed an infection (P = NS). Four patients had infected wounds when first seen; three received oral antibiotics; and one was admitted for intravenous antibiotics. Of the three on oral antibiotics, two were subsequently admitted to the hospital. Conclusions. We came to the following conclusions at the end of the study. (1) The majority of human bites in children are superficial and do not become infected. (2) Antibiotics do not appear to be useful in prophylaxis for minor bite wounds seen shortly after injury. (3) Follow-up is necessary for all bite wounds, since serious infection may develop, or an established, seemingly minor infection may worsen.     

Surgical versus conservative management of tongue lacerations in the acute care setting: A systematic review of the literature

ObjectiveThe objective of this study was to determine whether suturing or conservative management of tongue lacerations results in differences in wound healing and functional outcome. The secondary aim was to identify whether antibiotics are required in the treatment of tongue lacerations.MethodsStudies published between December 1954 and August 2020 were extracted from MEDLINE via PubMed, Embase via OVID, CINAHL via EBSCO, Web of Science, and the Cochrane Library and evaluated for inclusion based on predetermined inclusion and exclusion criteria by two independent reviewers in accordance with PRISMA guidelines.ResultsThe search yielded a total of 16,111 articles, 124 of which were evaluated by full-text review, resulting in 11 articles included in this systematic review representing 142 unique cases of tongue lacerations. At least 26 lacerations (18.3%) included penetration of the muscle layer of the tongue, and 24 (16.9%) were classified as full-thickness lacerations. Thirty-five of the 142 tongue lacerations (24.6%) were sutured. The remaining lacerations underwent some form of conservative management. The majority of studies reported excellent healing of tongue lacerations regardless of the management method, with minimal scarring and excellent return to normal functional status. No cases of infection were reported.ConclusionsCurrent literature is inconsistent with regards to indications and guidelines for primary repair of tongue lacerations. The majority of tongue lacerations reported in the literature heal with excellent outcomes regardless of management method. Physician judgement along with patient and parental preference based on potential risks of the procedure should be used when deciding whether a tongue laceration requires primary repair. Tongue lacerations in otherwise healthy individuals are at very low risk of infection.     

A prospective analysis of the use of octylcyanoacrylate tissue adhesive for wound closure in pediatric neurosurgery.

OBJECTIVE: Cyanoacrylate monomers have been developed for use as skin adhesives. Previous studies have demonstrated that using this skin adhesive for the closure of traumatic lacerations results in excellent cosmesis, decreased procedure-related pain and timesavings. SURGICAL TECHNIQUE: Octylcyanoacrylate skin adhesive is applied after the placement of deep fascial sutures with close approximation of the skin edges. The adhesive is applied in liquid form and polymerizes rapidly to solid form. Multiple layers are applied forming a hard impenetrable barrier. RESULTS: This technique was prospectively evaluated in the closure of 102 elective neurosurgical operations with 142 incisions: ventriculoperitoneal shunt insertion/revision (53%) and craniotomy for tumors (10%) were the commonest procedures. There were a total of 83 scalp, 36 abdominal, 8 neck, 6 chest and 6 lumbar incisions. The mean incision length was 5.1 cm (range 0.25-50 cm). Fifty-nine percent of the wounds had previous areas of operative incisions. Complications included 1 poor cosmetic result and 4 cerebrospinal fluid (CSF) leaks. Of the 4 patients with CSF leaks, 2 required operative wound revision, and 1 required ventriculoperitoneal shunting for hydrocephalus. CONCLUSION: Cyanoacrylate skin adhesive is a viable means of obtaining cosmetic wound closure. Its use requires attention to proper skin approximation and hemostasis. In our experience, propensity for CSF leakage especially in reoperative procedures is a relative contraindication.     

Comparison of a topical mixture of lidocaine and prilocaine (EMLA) versus 1% lidocaine infiltration on wound healing

We compared a eutectic mixture of lidocaine and prilocaine (EMLA, Astra Pharmaceuticals, Inc) with 1% lidocaine infiltration to determine the effect on wound healing in a prospective single blind study using the rat model. Thirty-six wounds were assessed. No clinical or histologic evidence of infection or necrosis was present in any wound. Five wounds (two in the lidocaine and three in the EMLA group, P = 1.0) demonstrated a widened scar owing to healing by secondary intention following suture disruption. There was no significant difference between groups in the degree of inflammation (P = 0.08). We conclude that EMLA does not affect wound healing adversely and is comparable to 1% lidocaine infiltration in the animal model. Further study to determine its anesthetic effect in laceration repair is presently being undertaken.     

Glass foreign body in the spinal canal of a child: case report and review of the literature

Retained foreign bodies pose a risk to the patient from the perspective of potential morbidity. We describe a previously healthy 8-year-old boy with head and back trauma from a glass picture frame that fell off the wall. He sustained a closed head injury and a back laceration several centimeters lateral to the spine. A persistent drainage from the back laceration contained glucose and protein levels consistent with cerebral spinal fluid. A foreign body was easily visible on subsequent plain radiograph. The glass foreign body was removed by neurosurgeons after computed tomography and magnetic resonance imaging clarified the exact location of the glass fragment. Physicians should have a low threshold for obtaining plain radiographs in patients with glass foreign bodies and consider that projectiles may rest some distance from the laceration site.     

Updates in wound management for the pediatrician

Lacerations are common in children, and skills in wound management, especially laceration repair, are important. The minimization of pain and anxiety should be considered an essential part of the procedure. Newer techniques using topical anesthetics and tissue adhesives have significantly simplified the process of laceration repair promoting application in office, clinic, and emergency department settings. In situations inappropriate for topical anesthesia and closure, the use of buffered lidocaine and attention to the technique of infiltration are important. Although infection is the most common complication, the percentage of lacerations, which become infected in children, is low. Antibiotic prophylaxis is seldom needed. Human and animal bites raise special concerns in the assessment for primary repair and prophylactic antibiotic use.     

Human bites in children. A six-year experience

Three hundred twenty-two human bites in children, occurring during a six-year period, were reviewed. The majority occurred during warm-weather months between 2 PM and 11 PM. The upper extremities (42%), face and neck (33%), and trunk (22%) were most commonly bitten. At the time of injury, children were most often engaged in fights (61%) or play (26%). Seventy-five percent of wounds were superficial abrasions, 13% were punctures, and 11% were lacerations. None of the 242 abrasions became infected as opposed to 38% of the punctures and 37% of the lacerations. Other factors associated with increased risk of infection were delay in initial physician assessment beyond 18 hours after injury, location of the bite on the upper extremities, and occurrence of injury during sports activities. Prophylactic use of penicillin was probably not effective in reducing infection rates in these children; however, prospective data are needed to properly address this issue.     

Reported incidence of injuries caused by street glass among urban children in Philadelphia

Setting—Children (18 years of age or younger) in the Ludlow community of Philadelphia.

Methods—A retrospective analysis of lacerations sustained while walking outdoors. A personal survey was conducted with 241 children on a door to door basis. Glass litter was measured by visual inspection of individual streets.

Results—Of 241 children, 83 (34%) had been cut at least once while walking outdoors. Of the 83, 62 were not wearing footwear at the time of injury. The majority of lacerations (86%) were caused by broken glass. Thirty nine of the 83 children received professional medical care for the laceration. Broken glass was estimated to be present on 30% of the outdoor walking area.

Conclusions—Broken glass is a significant health problem on littered urban streets. Preventive measures such as street cleaning, footwear education, and glass recycling incentives are needed to address this public health hazard.

     

Lacerations in urban children. A prospective 12-January study

We prospectively investigated the epidemiologic characteristics of all lacerations (N = 2834) repaired at the Children's Hospital of Philadelphia (Pa) during 1987 and identified common hazards and possible avenues of intervention. Two-year-old children incurred most injuries; males outnumbered females 2:1. Almost two thirds (61.8%) of all lacerations occurred from May through September, and 62.2% between 3 and 9 PM. Most injuries occurred indoors (47.0%), on the sidewalk or street (22.5%), or in the residential yard (13.0%). Injuries usually occurred during play (42.3%) or daily activity (32.1%); 1247 (44.0%) involved some sort of fall. Vectors most frequently causing injury were broken glass bottles (15.0%), wooden furniture (12.0%), and asphalt or concrete (11.0%). Broken glass bottles also most frequently inflicted injuries resulting in functional impairment (0.2%), hospitalization (0.9%), or both. Complications were seen in 8% of all lacerations. Our data confirm the importance of injury-prevention strategies aimed at reduction of discarded glass objects (ie, recycling legislation), improved furniture design, and improved municipal services (ie, street repair).     

Tracheobronchial rupture in a child following blunt trauma

A 6-year-old boy sustained a crush injury to the upper chest that resulted in a linear laceration of the membranous part of the lower trachea and right main stem bronchus. He presented with extensive subcutaneous emphysema, pneumomediastinum, and pneumoperitoneum. The diagnosis was indicated by a CT scan of the chest and confirmed by bronchoscopy. The trachea was intubated in the operating room after rigid bronchoscopy. Intraoperative leakage of gas from the tracheobronchial laceration was minimized by single left-lung manual ventilation and application of moist packs to the site of tracheal injury. Surgical repair was achieved with interrupted sutures of non-absorbable material; a pedicle pleural flap was used to buttress the suture line. The patient was discharged in good condition after 1 week. Complete healing of the anastomosis was attested at bronchoscopy 2 months postoperatively. The rarity of tracheobronchial lacerations in childhood is noted on review of the literature. Emphasis is placed on early recognition and expeditious management of tracheobronchial lacerations. Rarely, these lacerations have been reported to heal spontaneously.     

Costs of sedation using oral midazolam: money, time, and parental attitudes

OBJECTIVE: Many agents suitable for pediatric outpatient sedation have been identified and compared, but less data have appeared on the effect of sedation use on Emergency Department (ED) length of stay (LOS) or visit costs. We sought to discover the relationship between one commonly used method of sedation, orally administered midazolam, and ED LOS and visit costs. Parents were then surveyed to determine their attitudes toward sedation given knowledge of these costs. METHODS: All ED patients under 10 years of age seen in a pediatric ED during April and May of 1996 for repair of lacerations <2.5 cm in length were identified via retrospective chart review. Children were excluded if they had other significant injuries, received sedatives other than oral midazolam, or were repaired by non-ED physicians. Preliminary cost and LOS data from this review was used to create a parental survey measuring attitudes toward the costs of an unnamed form of sedation (not mentioning oral midazolam). A convenience sample of parents in an ED waiting room were asked if they would want sedation administered to a child needing sutures if this increased the visit cost by $100 and/or increased LOS by 30 minutes. Parents were then asked to re-answer these questions assuming that the sedation medication was effective only 50% of the time. RESULTS: Of 120 patients meeting entry criteria, 57 (48%) received oral midazolam. Children sedated with this agent were significantly younger (3.6 vs. 4.6 years, P = 0.015), had more layered repairs (30% vs. 14%, P = 0.047), and more facial lacerations (84% vs. 63%, P = 0.01) when compared with nonsedated patients. Mean LOS for patients with simple lacerations receiving oral midazolam increased by 17.1 minutes (P = 0.03) compared with nonsedated children; for layered repairs, the mean increase was 30.9 minutes (P<0.05). The use of oral midazolam did not effect physician charges, but did significantly increase mean combined nurse/hospital charges and total charges by 73 to 87 dollars, depending on laceration type (P<0.001 all cases). Of 81 parents surveyed, 81% said that they would be willing to wait 30 extra minutes for sedation to be used; this figure fell to 73% if sedation was effective 50% of the time. Seventy-five percent of parents were willing to pay $100 extra for sedation; 67% if sedation was effective only half the time. Willingness to endure a longer LOS or pay increased charges was not associated with parental sex or insurance status. CONCLUSION: The use of oral midazolam significantly increases ED visit LOS and cost. This information is important to review with parents when discussing sedation options. Up to one third of parents surveyed would not want to wait extra time or pay extra money for sedation to be administered, especially if the efficacy of the chosen method was not assured.
